E.L. Robinson completed construction plans for intersection upgrades to the Worthington Road and Big Walnut Road intersection. As part of the project, an analysis of intersection for various alternatives was completed. This project is located in Genoa Township and includes two-lane roads that intersect at a four-way stop at an angle of 53°±. Worthington Road is classified as an urban collector, while Big Walnut Road is classified as an urban minor arterial, with both containing graded shoulders, road side ditches, and no pedestrian facilities. As part of the project, a Feasibility Study was completed that included development of intersection alternatives, cost estimates, determining right of way impacts, traffic studies, turn lane development, and determining environmental impacts. Alternatives considered were curbed and uncurbed signalized intersections and roundabouts. Roundabout alternatives were designed to accommodate future widening along the Big Walnut Road corridor. In addition, intersection alternatives were developed at the Big Walnut Road and Ketterington Lane/Satinwood Drive intersection which also included signals and roundabout concepts. The signalized intersection option at Worthington Road and Big Walnut Road was selected as the preferred alternative. Construction plans included a two-way left turn lane on Big Walnut Road from Worthington Road to Ketterington Lane/Satinwood Drive. Accommodations for a future multi-lane path along Big Walnut Road were also provided.
